Description
Technical field
The invention belongs to field of sea water desalting technology, relate generally to a kind of solar energy sea water desalination apparatus and using method thereof.
Background technology
Along with the fast development of industry, water consumption is increasing, and the water resources in a lot of area becomes shortage.The shortage of water resources have impact on industrial expansion, even have impact on resident's orthobiosis.China is one of country of water resources shortage in the world, in the last few years, sharply reduces because environmental pollution result in Freshwater resources, and has had a strong impact on social steady progression.Shortage of fresh water has been a global problem, and the Freshwater resources how reasonable employment is limited are problems that countries in the world are all paid special attention to.
Current method for desalting seawater both domestic and external is many, comprises distillation method, cold method, reverse osmosis method, sun power method, low-temperature multi-effect method, electroosmose process etc.
Distillation method is distillation desalination process, and essence is exactly the forming process of water vapour, and its reason forms cloud as seawater by thermal evaporation, and cloud meets cold formation rain under certain condition.Vapour compression distillation method and multistage flash distillation method etc. is divided into according to equipment distillation method.
Cold method, namely freezing seawater makes it icing, and while liquid fresh water becomes solid ice, salt is separated.Cold method and distillation method have the drawback being difficult to overcome, and wherein distillation method can consume a large amount of energy and in instrument, produce a large amount of bird nests, and the fresh water obtained is also few; And cold method will consume the much energy equally, but the fresh water taste obtained is not good.
Reverse osmosis method, usually also known as ultra-filtration method, belongs to a kind of membrane sepn desalination process.Utilize only allow solvent through, do not allow solute through semi-permeable membranes, seawater and freshwater is separated.Under normal conditions, fresh water is diffused into seawater side by semi-permeable membranes, thus makes the liquid level of seawater side by rising, until certain height just stops.Now, the water column static pressure that seawater side exceeds is called osmotic pressure.If apply an external pressure being greater than penetration of sea water pressure to seawater side, the pure water so in seawater by reverse osmosis in fresh water.The great advantage of reverse osmosis method is energy-conservation.Its energy consumption is only 1/2 of electroosmose process, 1/40 of distillation method.
The key problem in technology of electroosmose process is the development of Novel ion exchange membrane.Ion-exchange membrane is the functional diaphragm of 0.5-1.0mm thickness, divides into positive ion exchange membrane (anode membrane) and anionic exchange membrane (cavity block) by its selective penetrated property.Electroosmose process is alternately arranged at the anode membrane and cavity block with selective penetrated property, forms multiple separate compartment seawater and desalinated, and adjacent compartments seawater concentrates, and fresh water is separated with condensed water.Electroosmose process not only can desalinize seawater, also can as the means of water conditioning, for reutilization of the sewage is made contributions.In addition, this method is also applied to concentrated, the Separation & Purification of the industries such as chemical industry, medicine, food more and more.
